  • Patent number: 11504456
    Abstract: A percutaneous drainage device for draining a fluid collection located under the skin of a patient is disclosed. The percutaneous drainage device includes a penetration component slidably engaged with a cannula. The penetration component has a piercing end adapted to penetrate tissue of a patient and introduce an open end of the cannula to a subcutaneous fluid collection site. The cannula may be held in place in the patient by an anchoring means. The cannula provides a passage through which a fluid collection may be drained from a patient. The cannula may be in fluid communication with a collection vessel, which collects fluid collection transported away from the subcutaneous fluid collection site.

  • Patent number: 11504457
    Abstract: A wound irrigation system and method of making and using. The system uses a pored, closed-ended delivery conduit to enhance the consistency and speed with which anti-microbial or related irrigation fluids may be delivered in order to promote cleansing, debridement and biofilm reduction in wounds. The ease of use of the system as a moist wound healing cascade makes it applicable to both in-home and in-facility environments that is not offered through traditional instillation negative pressure systems. In one form, the fluid delivery conduit is used as part of a dual-conduit approach in order to also help promote the removal of drainage, waste, irrigation overflow or other fluid from the wound. Utilization of such a pored, closed-ended delivery conduit in conjunction with a separate drainage conduit infusing helps reduce the frequency of dressing changes as well as the likelihood of microorganism formation and colonization.

  • Patent number: 11484688
    Abstract: Minimally invasive catheter relates to the field of eversible catheters. It is primarily intended for use as a urinary catheter, but is also usable in other fields. As a urinary catheter this minimally invasive catheter 1 used as an indwelling or intermittent catheter with transurethral or suprapubic approach. This catheter has specific technical solution for eversible motion where tubular membrane 2, attached between distal part 36a of the handle 36 and distal part 3a of the inner tube 3, can in one case free slide between these two parts and in another be fixed to form hermetically sealed space 14. Free sliding of membrane ensures eversible principle of motion during placement and withdrawal of the catheter 1. Fixation of membrane allows a formation of hermetically sealed space 14 with fluid to make catheter surface smoother and softer, and a balloon 33 to hold catheter 1 in place for prolonged period of time.

  • Patent number: 11464947
    Abstract: An aortic perfusion catheter is an apparatus that is used during surgery for acute ascending aortic dissection to reduce postoperative injuries from profound hypothermia, ischemia, and reperfusion. The apparatus may include at least one main cannula, an inflation cannula, a drainage cannula, and a balloon tamponade. The at least one main cannula helps maintain blood perfusion to the body during the procedure to reduce postoperative injuries. The inflation cannula enables the selective inflation and deflation of the balloon tamponade to facilitate the insertion and removal of the balloon tamponade along with the at least one main cannula within the descending thoracic aorta. The balloon tamponade prevents blood flow into the operative area to maintain the operative area clear during the procedure. The drainage cannula enables the drainage of blood that may escape the balloon tamponade as well as other bodily fluids.
